Identify files used in all queries

Using the following code you can identify files used in all queries in a library, library list or ALLUSR.
 
*************** CLP      *****************
             PGM        PARM(&LIB)
/* THE PARAMETER PASSED TO THIS PROGRAM COULD BE A SINGLE LIBRARY, *LIBL, +
    *ALLUSR.  */

             DCLF       FILE(QTEMP/QUERIES)

/* BECAUSE THE DCLF IS FOR A FILE IN QTEMP, THE NEXT STATEMENT WILL NEED +
    TO BE RUN MANUALLY TO CREATE THE FILE PRIOR TO COMPILING THIS PROGRAM.   +
    THE COMMAND CAN MANUALLY BE RUN TO CREATE THE FILE WITH JUST ONE     +
    QRYDFN RATHER THAN *ALL   */
